Statutory Residence Test (SRT) Details
๐ SRT Multi-Tier Breakdown
Under UK tax law introduced in Finance Act 2013, your UK tax residence status is determined strictly by the statutory Statutory Residence Test (SRT).
If you are classified as UK Tax Resident, HMRC taxes your worldwide income and capital gains. If you are Non-UK Resident, HMRC taxes ONLY your UK-sourced income.
โ๏ธ Statutory 3-Tier SRT Framework for 2026/27
The SRT evaluates residence using three statutory sequential tests:
Tier 1: Automatic Overseas Tests (Guaranteed Non-Resident)
You are automatically Non-UK Resident for the tax year if you meet ANY of these conditions:
- Under 16 Days: You spend fewer than 16 days in the UK during the tax year (or under 46 days if non-UK resident for 3 previous years).
- Full-Time Overseas Work: You work full-time overseas (averaging at least 35 hours per week) and spend fewer than 91 days in the UK.
Tier 2: Automatic UK Tests (Guaranteed UK Resident)
You are automatically UK Resident for the tax year if you meet ANY of these conditions:
- 183+ Days Rule: You spend 183 days or more in the UK during the tax year.
- Only Home Rule: Your only home is in the UK for at least 91 consecutive days.
Tier 3: Sufficient Ties Test Matrix
If you do not meet any automatic test, residence is determined by comparing your day count against your number of UK Ties:
- Family Tie: Spouse, civil partner, or minor children living in the UK.
- Accommodation Tie: Accessible UK accommodation available for 91+ days and used for at least 1 night.
- Work Tie: Working in the UK for at least 40 days (3+ hours per day).
- 90-Day Tie: Spending more than 90 days in the UK in either of the 2 preceding tax years.
- Country Tie: Spending more days in the UK than in any other single country.
๐ Practical SRT Worked Examples
Below are two worked calculation examples illustrating statutory residence determinations:
- Days Spent in UK: **45 Days**
- Number of UK Ties: **2 Ties**
- SRT Matrix Threshold for 46โ90 Days: Requires 3 Ties for UK Residence
Calculation: Spending 45 days with 2 ties falls below the 3-tie threshold. Result = Non-UK Resident.
- Days Spent in UK: **100 Days**
- Number of UK Ties: **3 Ties**
- SRT Matrix Threshold for 91โ120 Days: 2 or more ties triggers UK Residence
Calculation: Spending 100 days with 3 ties exceeds the 2-tie threshold. Result = UK Tax Resident.
๐ Common Pitfalls & Residence Warnings
- The Midnight Rule: A day spent in the UK counts as a UK day if you are present in the UK at midnight. Transiting through UK airports without clearing passport control does not count as a midnight stay.
- Temporary Repatriation Trap: Returning to the UK for extended family visits or medical treatment can accidentally trigger the Sufficient Ties matrix, making your entire overseas salary taxable in the UK.
- Split-Year Treatment Rules: If you move abroad to work full-time mid-tax year, you may qualify for Split-Year Treatment, splitting the tax year into a UK-resident period and a non-resident period.
